Human curiosity.
Machine intelligence.

I turn data into decisions, and into stories. Two decades building data science practice across borders, plus a podcast, a blog, and a shelf of stories.

02Side projects

Ideas, made real.

Apps I’ve built.

Each one is also a working use case of my AI and simulation work.

Eight things I wanted to exist, so I built them. One keeps the way a person thinks, so you can still talk with them. One asks an alien civilization what it thinks, and one lets you build a population of your own and ask it. One is a game about what the dead leave behind, and one about the cases a city forgot. One decides what to watch. One plans where to go. The last explains how markets work.

Voxari

Synthetic society

Someone asked

“Should the council levy a tax from the wealthiest inhabitants to ensure food and housing to all, even if this reduces the money available to invest in trade and new workshops?”

The Voxari answered

The Voxari support clearly. 40% are undecided.

From the latest weekly report

The week, explained: October 12 to 16, 2026

Longer-term Treasury yields fell over the week while the Federal Reserve's target range stayed at 3.75 to 4.00 percent, and the Bureau of Labor Statistics reported September 2026 inflation at 3.7 percent.

A semana, explicada: 12 a 16 de outubro de 2026

Os juros dos títulos do Tesouro americano de prazo mais longo caíram na semana, enquanto a faixa-alvo do Federal Reserve seguiu em 3,75 a 4,00 por cento, e o Bureau of Labor Statistics divulgou a inflação de setembro de 2026 em 3,7 por cento.

Mindarium

Artificial mind

Talk with Minds: thinkers from history, people you have lost, yourself, and the characters you write. Each Mind rests on a Mindprint, a portrait of how that person thinks, and every trait of a historical Mind cites the source it came from, so nobody is handed invented quotes. A family can build a Legacy Mind of someone who died from the stories they remember, and share it only with the people they choose. It runs in English, Portuguese, and Spanish. I built it because the way a person thinks is worth keeping, and a conversation keeps it better than a photo album.

Voxari

Synthetic society

A made-up alien civilization of 5,000 citizens, each with an age, a province, a family, beliefs and a page of their own. Ask them anything and they answer in seconds, province by province, on a live map. They also remember: they age, have children, die, drift in opinion, react to the news, and a council may even enact what you asked. It runs in English and Portuguese. I built it to see what typed, calibrated AI decisions look like at scale, and because a world that changes its mind was more interesting than a chart that doesn't.

Beta

Voxari Studio

Synthetic research

A platform for creating synthetic populations and running simulated studies with them, built on Voxari's engine. Describe the people you care about (customers, staff, a real place built from Census data) and Studio builds them, asks up to twelve questions, and shows who leans which way, by how much, and why, with honest error bars on every share. Finished studies can be published for anyone to read. It runs in English, Portuguese and Spanish, and it is in beta. It is a simulation, not a poll.

Live

The Hollow Dream

Narrative game

A story game you play in the browser. You work the night shift at the Bureau of the Hollow, a quiet afterlife office inside a dream that everyone shares. You rebuild a life from the objects someone left behind, talk with the dead, each one an AI-simulated individual, map recurring dreams and keep a lighthouse where ships arrive from other centuries. Other players leave traces in the same world, and every morning a Gazette reports what changed overnight. Claude tells the story and a typed AI judge decides what is true, so the world can surprise you without breaking its own rules. It runs in English, Portuguese and Spanish, and it is live. I built it because I wanted a game that feels like reading a good short story, one that remembers you the next night.

Vesperfall

True crime podcast game

A true crime podcast game you play in the browser. You join the Unit in a city of unfinished stories and reopen cold cases, some of which have waited forty years. Every witness and suspect is an AI-simulated individual you can actually talk to: they remember, hesitate and sometimes lie. You follow the evidence, use modern forensics on what time could not solve, and each case you work becomes a podcast episode made only for you. Other detectives leave quiet traces in the same files: a pencil mark, initials on a log. It runs in English and Portuguese.

Cosign

Taste engine

Movies, shows, and books recommended by your friends and no one else. Cosign learns whose taste actually overlaps with yours, asks what you thought after you watched, and keeps the whole thing private to your circle. I built it because an engine that recommends me things based on my trusted network of friends is better than some random website.

Private · family

Andata

Travel planning

A trip planner that builds the whole itinerary with you, city by city and day by day. It suggests activities and hotels, puts everything on a map, answers questions about your own trip through an AI assistant, and exports a PDF you can hand to whoever is travelling with you. I built it because planning a trip across a dozen browser tabs and a spreadsheet was driving me crazy. It runs privately for my family for now.

Teloria

Market education

Short, plain-language lessons on how financial markets work: stocks, bonds, funds, crypto, metals, retirement accounts, and taxes, in English, Spanish, and Portuguese. Delayed market data sits next to the lessons, a weekly report explains what moved and why, and a glossary untangles the jargon. It teaches and nothing else: it never executes trades, holds money, or gives personal advice. I built it because people are told to invest long before anyone explains what they are actually buying.

Books I've written

When I step away from data, I write fiction. Here's what's currently on the shelf.

04About

Between data and narrative.

I grew up in Brasília, the planned capital, all concrete and open sky. Born in Minas Gerais before that. Lived in São Paulo, Ceará, and Roraima at different points too. In 2014 IPC Global transferred me to the US. California first, then Massachusetts, then Georgia. My family and I have been in Johns Creek for a few years now and I still genuinely like it here.

I started coding at 8, on Basic and Cobol. Spent four years in Medical School before switching to Computer Science, which sounds like a detour but wasn't really. Biostatistics is what did it. One semester in and I knew that was where I wanted to go. I started my Master's at ITA, Instituto de Tecnologia Aeronáutica, one of Brazil's most selective engineering schools, roughly equivalent to MIT. Focused on artificial neural networks, back when that was still pretty niche. That was 22 years ago. I've been at IPC Global ever since. The work I'm most proud of is on the medical research side, data science applied to medicine. That's what got me into this in the first place.

I also played in bands in Brasília, with gigs and demos, though none of us were making a living from it. Rock mostly: The Beatles, Pink Floyd, Iron Maiden, Metallica. Still listen to all of them. I've also been writing fiction since I was 10. Gogol, Dostoyevsky, Kafka were the first writers that really got me. Five books out now. I'm honestly not sure the data work and the fiction are as different as they seem.

05Podcast

Two podcasts, two languages.

I co-host two shows about data, AI, and curiosity. One in Portuguese, one in English.

Intervalo de Confiança

Portuguese

A voyage through data science, AI, and curiosity, in Portuguese. Heard across Brazil, Portugal, and beyond.
